Have you ever felt exhausted all day, only to find yourself wide awake the moment you get into bed?
Perhaps your body feels tired, but your mind won't settle. You replay conversations, think about tomorrow's responsibilities or feel strangely alert just when you want to sleep. You might even find yourself worrying about not sleeping, making bedtime feel like another task you can't get right.
If this sounds familiar, you're not alone.
During perimenopause and menopause, changes in hormones can coincide with disrupted sleep, increased stress sensitivity, night-time waking and changes in mood. Everyday pressures, work, caring responsibilities and habits that once worked well may suddenly feel harder to manage.
One possible part of the picture is your body's stress-response system, which includes the hormone cortisol. Cortisol follows a natural daily rhythm, helping you become alert in the morning and generally declining towards the evening. When stress, disrupted routines or other factors interfere with sleep, you may find it harder to switch off at night.
However, feeling wired at bedtime doesn't automatically mean you have high cortisol. Hormonal changes, anxiety, hot flushes, medication, sleep disorders and other health factors can also contribute.
Understanding the possible reasons for your disrupted sleep can help you choose practical next steps rather than blaming yourself for not being able to switch off.
For a broader overview of the changes that can happen during this stage of life, start with my menopause symptoms guide.
Why You Can Feel Exhausted but Still Be Wide Awake
Feeling tired and being ready to sleep aren't always the same thing.
Physical tiredness is the feeling that you need rest. Sleepiness is the tendency to actually fall asleep. You can experience one without the other, particularly when stress, an irregular routine or repeated poor nights have left you feeling alert despite being exhausted.
During perimenopause and menopause, several factors may contribute.
1. Hormonal changes can disrupt your sleep
Oestrogen and progesterone change during the menopausal transition. These hormones interact with systems involved in temperature regulation, mood and sleep, although their effects vary between individuals.
You may notice that you wake more easily, feel less rested or find it harder to return to sleep after waking.
Hot flushes and night sweats can interrupt sleep directly. Some women also experience increased anxiety, changes in mood or a greater sense of being overwhelmed.
This doesn't mean that every sleep problem is hormonal. It does mean that if your sleep has changed alongside other menopause symptoms, it may be worth looking at the wider picture.
2. Stress can leave you feeling alert at the wrong time
Your stress-response system helps you respond to demands and potential threats. Cortisol is one of the hormones involved in that response.
Cortisol normally follows a daily rhythm, with levels generally higher around waking and lower towards the evening. Stress and sleep disruption can interact with this rhythm, although the relationship is more complex than simply having too much cortisol at night.
When your mind is busy anticipating tomorrow's challenges, or you have spent the day moving from one responsibility to another, you may find it difficult to settle when the day finally becomes quiet.
You might notice:
Replaying conversations or worrying about unfinished tasks.
Feeling tense even when you're physically exhausted.
Becoming frustrated because you aren't falling asleep.
Checking the time repeatedly and calculating how little sleep remains.
Feeling increasingly anxious about how you'll cope the next day.
These experiences can reinforce one another. Worry makes it harder to settle, poor sleep leaves you less able to cope with stress, and the following evening can bring renewed concern about sleeping.
This is one reason why focusing on sleep alone may not always be enough.
3. Poor sleep can make the next day harder
After a disrupted night, you may feel more irritable, emotionally sensitive or overwhelmed. Concentration can become harder, everyday problems may feel bigger and your usual coping strategies may seem less effective.
You may then rely on more caffeine, reduce your movement because you're exhausted or find yourself going to bed earlier in the hope of catching up.
These responses are understandable, but some can inadvertently make your sleep routine less consistent.
The aim isn't to follow a perfect set of rules. It's to identify which factors may be keeping the cycle going and make manageable adjustments.
Is It Cortisol, Anxiety or Something Else?
It's tempting to look for one explanation for feeling wired at night. In reality, several factors may be contributing at once.
Cortisol is part of your body's normal stress response, but you cannot reliably determine your cortisol levels from how you feel at bedtime. Feeling alert, anxious or unable to sleep doesn't prove that your cortisol is elevated.
Anxiety can involve racing thoughts, physical tension, a sense of apprehension or difficulty relaxing. It may become more noticeable during the menopause transition, particularly when sleep is already disrupted.
Hormonal symptoms, stressful circumstances and anxiety can overlap. Poor sleep may make anxiety harder to manage, while anxiety can make falling asleep more difficult.
Other possible contributors include:
Hot flushes and night sweats.
Caffeine, nicotine or alcohol.
An inconsistent sleep and wake schedule.
Medication or other health conditions.
Restless legs or sleep apnoea.
Persistent insomnia or another sleep disorder.
If sleep problems are ongoing, significantly affecting your daily life or accompanied by symptoms such as loud snoring, gasping during sleep or an overwhelming urge to move your legs at night, speak to your GP. These symptoms may need assessment rather than a lifestyle-only approach.
For a more detailed look at persistent sleep difficulties, read When Sleep Becomes the Enemy: Navigating Midlife Insomnia.
Why Waking at 3am Is a Different Sleep Problem
Feeling exhausted but alert at bedtime isn't quite the same as repeatedly waking in the early hours.
If you fall asleep reasonably easily but wake around 3am and struggle to get back to sleep, there may be different factors worth exploring, including night sweats, stress, your sleep schedule or other underlying causes.
Repeated early-morning waking can also occur alongside insomnia, but it doesn't automatically point to one particular hormone or explain what's happening in your body.
I've covered this more specifically in Waking at 3am in Menopause? One Overlooked Reason It May Be Happening.
That article focuses on early-morning waking. This one looks at the different experience of being tired but unable to switch off at bedtime.
How Movement May Help You Sleep Better
When you're exhausted, exercise may be the last thing you feel like doing. Yet regular movement can support physical and mental wellbeing, and some people find it helps them sleep more consistently.
The key is choosing an approach that suits your current energy, fitness and recovery needs.
1. Start with manageable daytime movement
You don't need to commit to an intensive exercise programme to begin.
A walk outdoors, a short cycle, swimming or another activity you enjoy can help you build regular movement into your day.
Morning daylight may also help reinforce your body's natural sleep–wake rhythm. If you can, spend some time outside earlier in the day and aim for a reasonably consistent wake-up time.
Start with something achievable. A short walk that fits your circumstances is a better starting point than a demanding routine that leaves you feeling depleted.
2. Include strength training if it suits you
Strength training supports muscle strength, physical function and bone health as you age. It can also be part of a balanced routine that supports your overall wellbeing during menopause.
However, resistance training isn't a guaranteed way to lower cortisol or cure insomnia. Its effects depend on factors such as exercise intensity, timing, recovery and your individual circumstances.
If you're new to strength training, begin at a level that feels manageable and build gradually.
My guide to strength training during menopause explains why maintaining strength matters and how it fits into the wider picture of midlife health.
3. Adjust the intensity to your energy levels
Hard exercise isn't inherently harmful, and you don't need to avoid it simply because you're experiencing menopause.
However, if you're sleeping poorly, already feel depleted or find that vigorous evening sessions leave you feeling more alert, experiment with adjusting the timing or intensity.
You could try a gentle walk, mobility work or a less demanding session on particularly tiring days.
Pay attention to how you feel afterwards and how your sleep responds. The aim is to find a sustainable routine, not to push through exhaustion.
4. Give yourself time to wind down
If you exercise late in the evening and notice that you struggle to settle afterwards, consider moving your session earlier or allowing more time between exercise and bedtime.
Some people tolerate evening exercise well; others find vigorous activity too stimulating close to sleep.
There is no single timing rule that works for everyone. Notice your own response and adjust accordingly.
Five Practical Ways to Wind Down at Night
You don't need an elaborate bedtime routine or a collection of supplements to begin supporting better sleep.
Try these five approaches and focus on the ones that make a noticeable difference for you.
1. Create a transition between the day and bedtime
If you've spent the day responding to messages, managing work or looking after other people, going straight from activity to bed may leave your mind racing.
Give yourself a short transition period.
You might prepare for the following morning, write down anything you need to remember or spend a few minutes reading something relaxing.
The aim is to reduce the feeling that you need to keep solving problems once you're in bed.
2. Keep your sleep schedule reasonably consistent
Try to wake at a broadly similar time each day, including after a poor night, where your circumstances allow.
A consistent wake-up time and exposure to daylight can help reinforce your body's daily rhythm.
You don't have to achieve perfect consistency. Shift work, caring responsibilities, illness and other demands can make regular routines difficult. Aim for a pattern that works in your real life.
3. Notice the effect of caffeine and alcohol
Caffeine can remain in your system for several hours and may interfere with sleep, even if you don't feel particularly stimulated by it.
If you struggle to fall asleep, experiment with having your last caffeinated drink earlier in the day.
Alcohol can make you feel sleepy initially but may disrupt sleep later in the night. If you notice a connection between drinking alcohol and waking, anxiety or feeling unrefreshed, try observing what happens when you reduce it or avoid it.
You can explore this further in Why Alcohol Affects You Differently in Perimenopause: Sleep, Mood and Recovery.
The goal is to understand your own patterns rather than judge yourself for your habits.
4. Make your bedroom comfortable
A bedroom that is dark, quiet and comfortably cool can support sleep.
If hot flushes or night sweats are waking you, consider practical adjustments such as breathable nightwear, lighter bedding or a fan if appropriate.
If noise, light or temperature regularly disturbs you, see whether one small change makes a difference.
These adjustments won't resolve every cause of insomnia, but they can remove avoidable obstacles to rest.
5. Use a simple relaxation practice
If you notice tension building at bedtime, try a few minutes of slow, comfortable breathing, gentle stretching or a short guided relaxation.
For example, breathe in gently and allow your exhalation to be slightly longer than your inhalation, without forcing the breath or holding it uncomfortably.
The purpose isn't to force yourself to sleep. It's to give yourself an opportunity to slow down.
If a particular technique makes you feel uncomfortable or more anxious, stop and try something else.
And remember: relaxation techniques are supportive tools, not a test you can fail. You don't need to make yourself feel calm before you're allowed to sleep.
What If You've Tried Everything and You're Still Not Sleeping?
This is often the point at which frustration sets in.
You've tried cutting back on caffeine, established an evening routine, bought supplements, downloaded sleep apps and attempted to manage stress. Yet you still find yourself lying awake or struggling through the following day.
If this sounds familiar, it may be time to step back and look at the whole pattern rather than adding another sleep tip to your list.
Consider the following questions:
Are hot flushes or night sweats waking you?
Do you struggle to fall asleep, wake repeatedly or both?
Does your mind become busy as soon as you get into bed?
Are you dealing with sustained pressure at work or home?
Has your sleep changed alongside other menopause symptoms?
Are you so tired that maintaining your usual routines has become difficult?
Have you discussed persistent sleep problems with your doctor?
Your answers may help you identify which area needs attention first.
If you suspect that menopause symptoms are affecting your sleep, a healthcare professional can discuss appropriate options, including whether menopause-specific treatment may be suitable. If anxiety, persistent insomnia or another health condition may be contributing, that deserves attention too.
You don't have to decide on your own which explanation is correct.
When Sleep Starts to Improve, the Wider Picture Matters Too
Sleep doesn't exist in isolation.
Your energy, nutrition, movement, stress, mood and everyday responsibilities can all influence how well you cope with the menopause transition.
That doesn't mean you need to overhaul every part of your life. In fact, trying to change everything at once can become another source of pressure.
A more useful approach is to understand what's happening, identify your priorities and choose changes that fit your circumstances.
For an example of how this can work in practice, read She Knew Sleep Was Important. The Problem Was Making the Right Changes Stick.
Sophie's story illustrates an important point: knowing what might help is not always the same as finding a realistic way to put it into practice.
Start with Menopause Essentials
If you're beginning to recognise that your sleep difficulties may be connected to a wider set of changes, Menopause Essentials is a practical next step to explore.
Rather than treating every symptom as a separate problem, it helps you look at the wider foundations of menopause wellbeing and consider where to focus your attention.
This can be a useful place to start if you want to build your understanding before deciding whether you need more personalised support.
You don't need to change everything at once. Start with the areas most relevant to you and build from there.
When Personalised Menopause Coaching Could Help
General advice can provide useful ideas, but applying those ideas when you're exhausted, busy or overwhelmed can be much harder.
Menopause coaching offers an opportunity to explore your priorities, identify practical barriers and develop realistic strategies that fit your circumstances.
For example, you might want to understand how your sleep, stress, movement and daily routines interact, or work out how to introduce changes without adding more pressure to an already demanding week.
Coaching is not a medical treatment for insomnia, anxiety or a hormonal condition. It doesn't replace assessment by your GP or other appropriate healthcare professionals. Instead, it can help you work on relevant lifestyle habits and behaviour changes alongside any medical support you receive.

Frequently Asked Questions
Why am I exhausted all day but wide awake at night?
Several factors may contribute, including menopause-related symptoms, stress, anxiety, an irregular sleep schedule, caffeine or other health conditions. Feeling wired at night doesn't by itself prove that your cortisol is high. If the problem persists, speak to your GP to explore possible causes and appropriate treatment.
Does menopause cause high cortisol at night?
Cortisol follows a natural daily rhythm and is involved in the body's response to stress. Hormonal changes and sleep disruption can interact with stress-response systems, but it isn't accurate to assume that every woman with menopause-related sleep problems has high evening cortisol. Symptoms alone cannot establish your cortisol levels.
Can exercise help me sleep better during menopause?
Regular movement can support general health and may help improve sleep for some people. Walking, strength training and other activities can all be useful, depending on your circumstances. If vigorous exercise close to bedtime seems to make you more alert, experiment with adjusting its timing or intensity.
Is feeling wired at night the same as anxiety?
Not necessarily. Anxiety can make it harder to settle, while hormonal symptoms, stress, disrupted routines and other factors can also contribute to feeling alert at bedtime. These experiences can overlap. If anxiety is persistent or affecting your daily life, speak to an appropriate healthcare professional.
What should I do if I keep waking at 3am?
Repeated early-morning waking can have several causes, including night sweats, stress, insomnia and other sleep or health conditions. It doesn't automatically mean that your cortisol is high. Read Waking at 3am in Menopause? One Overlooked Reason It May Be Happening for a more focused discussion, and speak to your GP if the problem persists or affects your wellbeing.
When should I seek medical advice for sleep problems?
Speak to your GP if sleep difficulties continue, significantly affect your daily life or occur alongside other concerning symptoms. Loud snoring, gasping during sleep, persistent low mood, significant anxiety or uncomfortable sensations in your legs at night may warrant further assessment. Your GP can help identify possible causes and discuss suitable options.
A final reminder: You don't have to solve every part of the menopause transition at once. Understanding your sleep pattern is a useful first step. From there, you can explore practical changes, seek appropriate medical advice and decide whether personalised support would help you move forward.
